Abstract
The prominent pathological feature of fatty liver disease lesions is excessive fat accumulation in lipid droplets in hepatocytes. Thus, developing fluorescent lipid droplet-specific probes with high permeability and a high imaging contrast provides a robust tool for diagnosing fatty liver diseases. Herein, we rationally developed a novel donor-acceptor lipophilic fluorescent probe ANI with high photostability for wash-free visualization of lipid droplets and fatty liver disease characteristics. ANI showed a typical twisted intramolecular charge transfer effect with very faint fluorescence in high-polar solvents, but dramatically boosted emissions in low-polar environments. The solvatochromic probe can selectively light up lipid droplets with a high contrast in a wash-free manner. Further use of ANI to reveal the excessive accumulation of lipid droplets with a significantly large size in the liver tissues from the fatty liver disease model mice was successfully demonstrated. The remarkable imaging performances rendered ANI an alternative tool for accurately evaluating fatty liver disease in intraoperative diagnosis.

Abstract
Studies on small molecule fluorescent probes for detecting G-quadruplexes DNA have bring about an extensive attention in recent years. In this paper, we designed and synthesized three benzothiazole derivatives named 2a-2c under moderate reaction conditions and investigated their interactions with DNA (single-stranded, duplex, i-motif and G-quadruplex) and distribution in living cell. Three compounds present a large Stokes shift (∼90 nm) and a weak red fluorescence emission, and they exhibit a good selectivity and sensitive turn-on fluorescence response for the promoter G-quadruplex DNA (bcl-2, c-myc and c-kit 2) and mitochondria G-quadruplex (KSS). The affinity of 2a and 2b with N-alkyl side chain group to DNA is stronger than that of 2c with an anion group, therefore, they also increase the stability of the G-quadruplex structure. 2b induces the conformational change of both bcl-2 and KSS G-quadruplexes, while all compounds induce the folding of bcl-2 from the coiled structure to the hybrid G-qrudruplex. Three compounds interact with the G-quadruplex DNA mainly by end-stacking mode. Furthermore, MTT assays and confocal fluorescence images show that these compounds can enter the living HepG2 cells with low cytotoxicity. 2a-2c are mainly located in the mitochondrion and interacted with mitochondria G-quadruplex DNA, while only weak fluorescence can be found in cell nucleus. In a word, 2a-2c can be implied in image of G-quadruplex DNA in living cells.

Abstract
Environmentally sensitive fluorescent probes (including AIEgens) play pivotal roles in numerous biological studies. Many of these functional materials are developed based on the twisted intramolecular charge transfer (TICT) mechanism. However, the TICT tendency of dialkylated amino groups in biocompatible main-stream fluorophores (i.e., coumarins and rhodamines) is weak, limiting their sensitivities. Herein, by replacing dialkylated amino donors with an N-methylpyrrole group to enhance TICT, a simple and general method to engineer highly environmentally sensitive fluorescent probes is reported. This method yields a platter of colorful fluorescent probes that demonstrates outstanding polarity and viscosity sensitivity with large turn-on ratios (up to 191 times for polarity and 14 times for viscosity), as well as distinct aggregation-induced emission (AIE) characteristics. The utilities of these probes in both wash-free bioimaging and protein detections are also successfully demonstrated. It is expected that this molecular design strategy will inspire the creation of many environmentally sensitive probes.

Abstract
Luminogens characteristic of aggregation-induced emission (AIEgens) have been extensively exploited for the development of imaging-guided photodynamic therapeutic (PDT) agents. However, intramolecular rotation of donor–acceptor (D–A) type AIEgens favors non-radiative decay of photonic energy which results in unsatisfactory fluorescence quantum and singlet oxygen yields. To address this issue, we developed several molecularly engineered AIEgens with partially “locked” molecular structures enhancing both fluorescence emission and the production of triplet excitons. A triphenylphosphine group was introduced to form a D–A conjugate, improving water solubility and the capacity for mitochondrial localization of the resulting probes. Experimental and theoretical analyses suggest that the much higher quantum and singlet oxygen yield of a structurally “significantly-locked” probe (LOCK-2) than its “partially locked” (LOCK-1) and “unlocked” equivalent (LOCK-0) is a result of suppressed AIE and twisted intramolecular charge transfer. LOCK-2 was also used for the mitochondrial-targeting, fluorescence image-guided PDT of liver cancer cells. Luminogens characteristic of aggregation-induced emission (AIEgens) have been engineered for the development of imaging-guided photodynamic therapeutic (PDT) agents.![]()

Paclitaxel derivative-based liposomal nanoplatform for potentiated chemo-immunotherapy. J Control Release 2021; 341:812-827.

Abstract
The combination of chemotherapy with the immune checkpoint blockade (ICB) therapy is bringing a tremendous hope in the treatment of malignant tumors. However, the treatment efficacy of the existing chemo-immunotherapy is not satisfactory due to the high cost and immunogenicity of ICB antibodies, low response rate to ICB, off-target toxicity of therapeutic agents, and low drug co-delivery efficacy. Therefore, a high-efficient nanosystem combining the delivery of chemotherapeutics with small molecule ICB inhibitors may be promising for an efficient cancer therapy. Herein, a novel reactive oxygen species (ROS)-activated liposome nanoplatform was constructed by the loading of a ROS-sensitive paclitaxel derivative (PSN) into liposomes to overcome the difficulties on delivering paclitaxel mostly represented by premature drug release and a low amount accumulated into the tumor. The innovative liposomal nanosystem was rationally designed by a remote loading of BMS-202 (a small molecule PD-1/PD-L1 inhibitor) and PSN into the liposomes for a ROS-sensitive paclitaxel release and sustained BMS-202 release. The co-loaded liposomes resulted in a high co-loading ability and improved pharmacokinetic properties. An orthotopic 4 T1 breast cancer model was used to evaluate the efficiency of our nanoplatform in vivo, resulting in a superior antitumor activity. The antitumor immunity was activated by paclitaxel-mediated immunogenic cell death, while BMS-202 continuously blocked PD-L1 which could be up-regulated by paclitaxel in tumors to increase the response to ICB and further recover the host immune surveillance. These results revealed that this dual-delivery liposome might provide a promising strategy for a high-efficient chemo-immunotherapy, exhibiting a great potential for clinical translation.

Abstract
The twisted intramolecular charge transfer (TICT) mechanism has guided the development of numerous bright and sensitive fluorophores. This review briefly overviews the history of establishing the TICT mechanism, and systematically summarizes the molecular design strategies in modulating the TICT tendency of various organic fluorophores towards different applications, along with key milestone studies and representative examples. Additionally, we also succinctly review the twisted intramolecular charge shuttle (TICS) and twists during photoinduced electron transfer (PET), and compare their similarities and differences with TICT, with emphasis on understanding the structure-property relationships between the twisted geometries and how they can directly affect the fluorescence of the molecules. Such structure-property relationships presented herein will greatly aid the rational development of fluorophores that involve molecular twisting in the excited state.

Although super-resolution imaging offers an opportunity to visualize cellular structures and organelles at the nanoscale level, cellular heterogeneity and unpredictability still pose a significant challenge in the dynamic imaging of live cells. It is thus vital to develop better-performing and more photostable probes for long-term super-resolution imaging. Herein, we report a probe, LD-FG, for imaging lipid droplet (LD) dynamics using structured illumination microscopy (SIM). LD-FG allows wash-free imaging of LDs, owing to a hydrogen-bond sensitive fluorogenic response. The replacement of photobleached LD-FG by intact probe molecules outside the LDs ensures the long-time stability of the fluorescence imaging. With this buffering fluorogenic probe, fast and unpredictable dynamic processes of LDs can be visualized. Using this probe, two LD coalescence modes were discovered. The dynamic imaging also allowed us to propose a new model of LD maturation during adipocyte differentiation, i.e., a fast LD coalescence followed by a slow ripening step. The excellent performance of LD-FG makes the buffer strategy an effective method for designing fluorescent probes for cell dynamic imaging.

Abstract
Graphene oxide-rhodamine B hydrazide (GO-RhB) nanocomposite was prepared by a simple chemical method and characterized by various spectroscopic and analytical techniques. GO-RhB nanocomposite potentially detects Cr3+ ion (excitation/emission = 550 nm/572 nm) via fluorescence turn "on-off" approach. This composite showed high binding affinity (106 M-1) with Cr3+ and a+ limit of detection (LOD) down to picomolar concentration (LOD = 85.6 pM). As far as we know, this is the first report for the sensing of Cr3+ ion at picomolar concentration. GO-RhB selectively senses Cr3+ ion without any interference of other coexisting metal ions. In addition, this composite exhibited the dynamic nature of quenching in the presence of Cr3+ ion, which is confirmed by the Stern-Volmer plot, fluorescence temperature profiles, and decay time experiments. The GO-RhB nanocomposite-based fluorescent probe was successfully applied to the quantitative detection of Cr3+ ion in milk sample (linear range = 2 to 10 nM) with better performance than other existing methods. Besides, this GO-RhB composite showed better antibiofilm activity against Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA) by using the Congo red agar and tube method.

Abstract
The hydroxyl radical (·OH), one of the reactive oxygen species (ROS) in biosystems, is found to be involved in many physiological and pathological processes. However, specifically detecting endogenous ·OH remains an outstanding challenge owing to the high reactivity and short lifetime of this radical. Herein, inspired by the scavenging mechanism of a neuroprotective drug edaravone toward ·OH, we developed a new ·OH-specific fluorescent probe RH-EDA. RH-EDA is a hybrid of rhodamine and edaravone and exploits a ·OH-specific 3-methyl-pyrazolone moiety to control its fluorescence behavior. RH-EDA itself is almost nonfluorescent in physiological conditions, which was attributed to the formation of a twisted intramolecular charge transfer (TICT) state upon photoexcitation and the acylation of its rhodamine nitrogen at the 3' position. However, upon a treatment with ·OH, its edaravone subunit was converted to the corresponding 2-oxo-3-(phenylhydrazono)-butanoic acid (OPB) derivative (to afford RH-OPB), thus leading to a significant fluorescence increase (ca. 195-fold). RH-EDA shows a high sensitivity and selectivity to ·OH without interference from other ROS. RH-EDA has been utilized for imaging endogenous ·OH production in living cells and zebrafishes under different stimuli. Moreover, RH-EDA allows a high-contrast discrimination of cancer cells from normal ones by monitoring their different ·OH levels upon stimulation with β-Lapachone (β-Lap), an effective ROS-generating anticancer therapeutic agent. The present study provides a promising methodology for the construction of probes through a drug-guided approach.

Abstract
Understanding the mechanisms of aggregation-induced emission (AIE) is essential for the rational design and deployment of AIEgens toward various applications. Such a deep mechanistic understanding demands a thorough investigation of the excited-state behaviors of AIEgens. However, because of considerable complexity and rapid decay, these behaviors are often not experimentally accessible and the mechanistic comprehension of many AIEgens is lacking. Herein, utilizing detailed quantum chemical calculations, we provide insights toward the AIE mechanism of 1-(N,N-dialkylamino)-naphthalene (DAN) derivatives. Our theoretical analysis, corroborated by experimental observations, leads to the discovery that modulating the formation of the twisted intramolecular charge transfer (TICT) state (caused by the rotation of the amino groups) and managing the steric hindrance to minimize solid-state intermolecular interactions provides a plausible explanation for the AIE characteristics of DAN derivatives. These results will inspire the deployment of the TICT mechanism as a useful design strategy toward AIEgen development.

Abstract
A new class of NIR distyryl Bodipy fluorescent dyes were developed with sulfone- and quaternary ammonium-modified piperidines as auxochromes instead of conventional dialkylamino auxochromes. Such modification markedly improved the fluorescence quantum yields due to the efficient inhibition of the twisted intramolecular charge transfer (TICT) state. Based on the dye platform, we developed a new fluorescent H2O2 probe via self-immolative chemistry, and confirmed its capability to sensitively and selectively sense H2O2in vitro and in vivo.

Abstract
Zinc biology, featuring intertwining signaling networks and critical importance to human health, witnesses exciting opportunities in the big data era of physiology. Here, we report a class of red- and far-red-emitting Zn2+ probes with Kd values ranging from 190 nM to 74 μM, which are particularly suitable for real-time monitoring the high concentration of Zn2+ co-released with insulin during vesicular secretory events. Compared to the prototypical rhodamine-based Zn2+ probes, the new class exploits morpholino auxochromes which eliminates phototoxicity during long-term live recording of isolated islets. A Si-rhodamine-based Zn2+ probe with high turn-on ratio (>100), whose synthesis was enabled by a new route featuring late-stage N-alkylation, allowed simultaneous recording of Ca2+ influx, mitochondrial signal, and insulin secretion in isolated mouse islets. The time-lapse multicolor fluorescence movies and their analysis, enabled by red-shifted Zn2+ and other orthogonal physiological probes, highlight the potential impact of biocompatible fluorophores on the fields of islet endocrinology and system biology.

Abstract
A series of new naphthalimide and phenothiazine-based push-pull systems (NPI-PTZ1-5), in which we structurally modulate the oxidation state of the sulfur atom in the thiazine ring, i.e., S(II), S(IV), and S(VI), was designed and synthesized by the Pd-catalyzed Sonogashira cross-coupling reaction. The effect of the sulfur oxidation state on the spectral, photophysical, and electrochemical properties was investigated. The steady-state absorption and emission results show that oxygen functionalization greatly improves the optical (absorption coefficient and fluorescence efficiency) and nonlinear optical (hyperpolarizability) features. The cyclic voltammetry experiments and the quantum mechanical calculations suggest that phenothiazine is a stronger electron donor unit relative to phenothiazine-5-oxide and phenothiazine-5,5-dioxide, while the naphthalimide is a strong electron acceptor in all cases. The advanced ultrafast spectroscopic measurements, transient absorption, and broadband fluorescence up conversion give insight into the mechanism of photoinduced intramolecular charge transfer. A planar intramolecular charge transfer (PICT) and highly fluorescent excited state are populated for the oxygen-functionalized molecules NPI-PTZ2,3 and NPI-PTZ5; on the other hand, a twisted intramolecular charge transfer (TICT) state is produced upon photoexcitation of the oxygen-free derivatives NPI-PTZ1 and NPI-PTZ4, with the fluorescence being thus significantly quenched. These results prove oxygen functionalization as a new effective synthetic strategy to tailor the photophysics of phenothiazine-based organic materials for different optoelectronic applications. While oxygen-functionalized compounds are highly fluorescent and promising active materials for current-to-light conversion in organic light-emitting diode devices, oxygen-free systems show very efficient photoinduced ICT and may be employed for light-to-current conversion in organic photovoltaics.

Abstract
Alzheimer's disease (AD) and Parkinson's disease (PD) are chronic neurodegenerative diseases with high morbidity and mortality. Homocysteine (Hcy), cysteine (Cys), and glutathione (GSH) are closely related to AD and PD. However, the dynamics of Hcy, Cys, and GSH in the brain tissues and the potential pathogenesis between Cys/Hcy/GSH with AD and PD remain unclear. Herein, a novel fluorescent probe 1 with multiple binding sites was rationally designed and exploited for the direct quantification of serum total Hcy and Cys along with superior optical properties. Importantly, differentiation and simultaneity fluorescence imaging of Cys, Hcy, and GSH dynamics were achieved in living cells, tissues, and mouse models of AD and PD with this probe, providing direct evidences for the relationship between Hcy/Cys/GSH and AD/PD for the first time. In addition, pathogenesis studies demonstrated that elevated Hcy and Cys levels are closely related to imbalanced redox homeostasis, increased amyloid aggregates, and nerve cell cytotoxicity. These findings will greatly promote the understanding of the functions of Hcy/Cys/GSH in Alzheimer's and Parkinson's diseases, demonstrating clinical promise for the early diagnosis and prevention of AD and PD.

Abstract
The endoplasmic reticulum (ER) transforms its morphology to fit versatile cellular functions especially under stress conditions. Since various ER stresses are critical pathophysiological factors, the precise observations of ER can provide insights into disease diagnoses and biological researches. Live-cell super-resolution imaging is highly expected for uncovering microstructures of ER. However, to achieve this, there remains a big challenge in how to efficiently label ER with advanced fluorophores. Herein, we report a new SNAP-tag fluorescent probe, namely, CLP-TMR, for specific and high-density labeling of the newly constructed dual ER-signal (targeting and retention) peptides fused-SNAP proteins. This hybrid labeling system integrating chemical probes with genetically encoded techniques enables molecular position reconstructions of ER morphologies through direct stochastic optical reconstruction microscopy (dSTORM) imaging. The super-resolution imaging reveals several never-known ultrastructural changes responding to different ER stresses, i.e. the formation of peripheral ER sheets to restore the immunogenicity, and the long flattened ER tubules under inflammation.

Abstract
The evolution of super-resolution imaging techniques, especially single-molecule localization microscopy, demands the engineering of switchable fluorophores with labeling functionality. Yet, the switching of these fluorophores depends on the exterior conditions of UV light and enhancing buffers, which is bioincompatible for living-cell applications. Herein, to surpass these limitations, a nitroso-caging strategy is employed to cage rhodamines into leuco forms, which for the first time, is discovered to uncage highly bright zwitterions by green light. Further, clickable construction grants the specificity and versatility for labeling various components in living cells. The simultaneous photoactivation and excitation of these novel probes allow for single-laser super-resolution imaging without any harmful additives. Super-resolution imaging of microtubules in fixed cells or mitochondria and the distribution of glycans and H2B proteins in living cells are achieved at a molecular scale with robust integrity. We envision that our nitroso-caging probes would set a platform for the development of future visible-activatable probes.

Abstract
A strategy to implement four members of the classic coal-tar dye family, Michler's ketone, methylene blue, rhodamine B, and crystal violet, into [Pd2 L4 ] self-assemblies is introduced. Chromophores were incorporated into bis-monodentate ligands using piperazine linkers that allow to retain the auxochromic dialkyl amine functionalities required for intense colors deep in the visible spectrum. Upon palladium coordination, ligands with pyridine donors form lantern-shaped dinuclear cages while quinoline donors lead to strongly twisted [Pd2 L4 ] helicates in solution. In one case, single crystal X-ray diffraction revealed rearrangement to a [Pd3 L6 ] ring structure in the solid state. For nine examined derivatives, showing colors from yellow to deep violet, CD spectroscopy discloses different degrees of chiral induction by an enantiomerically pure guest. Ion mobility mass spectrometry allows to distinguish two binding modes. Self-assemblies based on this new ligand class promise application in chiroptical recognition, photo-redox catalysis and optical materials.

Abstract
Newly emerging super-resolution imaging techniques provide opportunities for precise observations on cellular microstructures. However, they also impose severe demands on fluorophores. Here, we develop a new series of NIR xanthene dyes, named as KRhs, by replacing the 10-position O of rhodamines with a cyclo-ketal. KRhs display an intense NIR emission peak at 700 nm with fluorescence quantum yields up to 0.64. More importantly, they, without the aid of enhancing buffer, exhibit stochastic fluorescence off-on switches to support time-resolved localization of single fluorophore. KRhs are functionalized into KRh-MitoFix, KRh-Mem and KRh-Halo that demonstrate mitochondria, plasma membrane and fusion protein targeting ability, respectively. Consequently, these KRh probes demonstrate straightforward usage for super-resolution imaging of these targets in live cells. Therefore, KRhs merit future development for fluorescence labeling and super-resolution imaging in the NIR region.

Abstract
Herein, we report our work exploring the essential requirements for fluorophore selection during the development of various fluorescence applications. We assembled a library of chromone-derived fluorophores with diverse structure-fluorescence properties, which allowed us to choose the fluorophore pairs with similar structures but differing fluorescence properties and compared the performance of the selected fluorophore pairs in three types of commonly used fluorescence applications. We found that the selection standard of a suitable fluorophore is variable depending on the application. (1) In fluorescence imaging, fluorophores with strong and constant fluorescence under various conditions, such as a large pH range, are preferred. Notably, (2) in the detection of bioactive species, fluorophores with relatively lower fluorescence quantum yield favor the detection sensitivity. Furthermore, (3) in enzymatic assays employing fluorescence, the key parameter is the binding affinity between the fluorophore and the enzyme.

Abstract
Molecular engineering of fluorophore scaffolds, especially heteroatom replacement, is a promising method to yield novel fluorophores with tailored properties for various applications. Yet, molecular origins of the distinct fluorescent properties in newly developed SCOTfluors, i. e., varied emission wavelengths, distinct quantum yields, and fluorogenicity, remain elusive. Such understanding, however, is critical for the rational molecular engineering of high-performance fluorophores. Herein, we employed quantum chemical calculations to understand the structure-property relationships of nitrobenzoxadiazole (NBD)-like SCOTfluors. Our findings are important not only for the rational deployment of SCOTfluors, but also for the effective modifications of other fluorophore scaffolds, for satisfying the increasingly diversified requirements of bioimaging and biosensing applications.

Abstract
Lysosomes are membrane-enclosed small spherical cytoplasmic organelles. Malfunctioning and abnormalities in lysosomes can cause a plethora of neurodegenerative diseases. Consequently, understanding the structural information on lysosomes down to a subnanometer level is essential. Recently, super-resolution imaging techniques enable us to visualize dynamical processes occurring in suborganelle structures inside living cells down to subnanometer accuracy by breaking the diffraction limit. A brighter and highly photostable fluorescent probe is essential for super-resolution microscopy. In this regard, this mini-review deals with the various types of super-resolution techniques and the probes that are used to specifically stain and resolve the structure of the lysosomes.

Abstract
Near-infrared (NIR) fluorescence imaging (FI) has become a research hotspot because of its distinctive imaging properties: high temporal resolution and sensitivity. Especially in recent years, with the research focus of NIR FI shifting to the NIR-II region, which has better imaging performance, it is expected that NIR FI will find significant applications in the field of in vivo imaging. One of the most crucial directions for research into NIR-II FI is the promotion of novel NIR-II fluorophores with superior imaging properties. The remarkable advantages of organic NIR-II fluorophores in biosafety make them more promising than other fluorescent materials in certain applications. But serious defects in their fluorescence performance preclude particular imaging effects and limit imaging functions. In this review, we summarize and discuss the recent leading literature on overcoming the defects of organic NIR-II fluorophores, demonstrating the potential for further improving their imaging properties. In addition, we cover the functions of NIR-II FI that are promoted by the development of fluorophores, notably including its outlook on molecular imaging in vivo.

Abstract
Fluorescence imaging has made tremendous inroads toward understanding the complexity of biological systems, but in vivo deep-tissue imaging remains a great challenge due to the optical opacity of biological tissue. Recent improvements in laser and detector manufacturing have allowed the expansion of nonlinear and linear fluorescence imaging to the underexplored "tissue-transparent" second near-infrared (NIR-II; 1000-1700 nm) window, opening up new opportunities for optical access deep inside opaque tissue. Molecular fluorophores have historically played a major role in fluorescence bioimaging. It is increasingly important to design new molecular fluorophores to fully unlock the potential of NIR-II imaging techniques. In this outlook, we give an overview of the novel molecular fluorophores developed for deep-tissue bioimaging in the past five years and discuss their pros and cons in applications. Guidelines for designing new molecular fluorophores with the desirable properties are also provided.

Abstract
Fluorescent probes that light-up upon reaction with complementary bioorthogonal reagents are superior tools for no-wash fluorogenic bioimaging applications. In this work, a thorough study is presented on a set of seventeen structurally diverse coumarin-tetrazine probes that produce fluorescent dyes with exceptional turn-on ratios when reacted with trans-cyclooctene (TCO) and bicyclononyne (BCN) dienophiles. In general, formation of the fully aromatic pyridazine-containing dyes resulting from the reaction with BCN was found superior in terms of fluorogenicity. However, evaluation of the probes in cellular imaging experiments revealed that other factors, such as reaction kinetics and good cell permeability, prevail over the fluorescence turn-on properties. The best compound identified in this study showed excellent performance in live cell-labeling experiments and enabled no-wash fluorogenic imaging on a timescale of seconds.

Abstract
Modern fluorescence-imaging methods promise to unveil organelle dynamics in live cells. Phototoxicity, however, has become a prevailing issue when boosted illumination applies. Mitochondria are representative organelles whose research heavily relies on optical imaging, yet these membranous hubs of bioenergy are exceptionally vulnerable to photodamage. We report that cyclooctatetraene-conjugated cyanine dyes (PK Mito dyes), are ideal mitochondrial probes with remarkably low photodynamic damage for general use in fluorescence cytometry. In contrast, the nitrobenzene conjugate of Cy3 exhibits enhanced photostability but unaffected phototoxicity compared to parental Cy3. PK Mito Red, in conjunction with Hessian-structural illumination microscopy, enables 2000-frame time-lapse imaging with clearly resolvable crista structures, revealing rich mitochondrial dynamics. In a rigorous stem cell sorting and transplantation assay, PK Mito Red maximally retains the stemness of planarian neoblasts, exhibiting excellent multifaceted biocompatibility. Resonating with the ongoing theme of reducing photodamage using optical approaches, this work advocates the evaluation and minimization of phototoxicity when developing imaging probes.

Abstract
Photochemical reactions can be designed to convert either irreversibly or reversibly a nonemissive reactant into an emissive product. The irreversible disconnection of a photocleavable group from an emissive chromophore or the reversible interconversion of a photochromic component is generally exploited to implement these operating principles for fluorescence switching. In both instances, the interplay of activating radiation, to convert the nonemissive state into the emissive species, and exciting radiation, to produce fluorescence from the latter, can be exploited to switch fluorescence on in a given area of interest at a precise interval of time. Such a level of spatiotemporal control provides the opportunity to reconstruct sub-diffraction images with resolution at the nanometer level. Indeed, closely-spaced emitters can be switched on under photochemical control at distinct intervals of time and localized independently at the single-molecule level. In combination with appropriate intracellular targeting strategies, some of these photoactivatable fluorophores can be switched and localized inside live cells to permit the visualization of sub-cellular structures with a spatial resolution that would be impossible to achieve with conventional fluorophores. As a result, photoactivatable fluorophores can become invaluable probes for the implementation of super-resolution imaging schemes aimed at the elucidation of the fundamental factors controlling cellular functions at the molecular level.

Abstract
Photoinduced electron transfer (PET) is one of the most important mechanisms for developing fluorescent probes and biosensors. Quantitative prediction of the quantum yields of these probes and sensors is crucial to accelerate the rational development of novel PET-based functional materials. Herein, we developed a general descriptor (ΔE) for predicting the quantum yield of PET probes, with a threshold value of ∼0.6 eV. When ΔE < ∼0.6 eV, the quantum yield is low (mostly <2%) due to the substantial activation of PET in polar environments; when ΔE > ∼0.6 eV, the quantum yield is high because of the inhibition of PET. This simple yet effective descriptor is applicable to a wide range of fluorophores, such as BODIPY, fluorescein, rhodamine, and Si-rhodamine. This ΔE descriptor enables us not only to establish new applications for existing PET probes but also to quantitatively design novel PET-based fluorophores for wash-free bioimaging and AIEgen development.

Abstract
Optical diffraction fundamentally limits the spatial resolution of conventional fluorescence images to length scales that are, at least, 2 orders of magnitude longer than the dimensions of individual molecules. As a result, the development of innovative probes and imaging schemes to overcome diffraction is very much needed to enable the investigation of the fundamental factors regulating cellular functions at the molecular level. In this context, the chemical synthesis of molecular constructs with photoactivatable fluorescence and the ability to label subcellular components of live cells can have transformative implications. Indeed, the fluorescence of the resulting assemblies can be activated with spatiotemporal control, even in the intracellular environment, to permit the sequential localization of individual emissive labels with precision at the nanometer level and the gradual reconstruction of images with subdiffraction resolution. The implementation of these operating principles for subdiffraction imaging, however, is only possible if demanding photochemical and photophysical requirements to enable photoactivation and localization as well as stringent structural requisites to allow the covalent labeling of intracellular targets in live cells are satisfied. Because of these complications, only a few synthetic photoactivatable fluorophores with appropriate performance for live-cell imaging at the nanoscale have been developed so far. Significant synthetic efforts in conjunction with spectroscopic analyses are still very much needed to advance this promising research area further and turn photoactivatable fluorophores into the imaging probes of choice for the investigation of live cells.

Abstract
The plasma membrane (PM) plays a major role in many biological processes; therefore, its proper fluorescence staining is required in bioimaging. Among the commercially available PM probes, styryl dye FM1-43 is one of the most widely used. In this work, we demonstrated that fine chemical modifications of FM1-43 can dramatically improve the PM staining. The newly developed probes, SP-468 and SQ-535, were found to display enhanced photophysical properties (reduced cross-talk, higher brightness, improved photostability) and, unlike FM1-43, provided excellent and immediate PM staining in 5 different mammalian cell types including neurons (primary culture and tissue imaging). Taking advantage of these features, we successfully used SP-468 in STED super resolution neuronal imaging. Additionally, we showed that the new probes displayed differences in their internalization pathways compared to their parent FM1-43. Finally, we showed that the new probes kept the ability to stain the PM of plant cells. Overall, this work presents new useful probes for PM imaging in cells and tissues and provides insights on the molecular design of new PM targeting molecules.
